Abstract

Abstract: In order to analyze its force under different sections and arch span ratio of the Antisymmetric arch tower cable-stayed bridge, the paper takes an anti-symmetric arch tower cable-stayed bridge as an engineering example. Considering the effect of dead load and temperature, finite software is used to calculate the stress of the arch tower and deflection of the deck and its corresponding dynamic characteristics under different types of arch sections and different rise-span ratio of the arch. The results show that the circular cross-section has better mechanical performance compared with other types of arches tower section with the same cross-sectional area. When it is circular cross section arch tower, the bridge deflection is smaller, while the tower arch maximum stress can be significantly reduced. In the same condition when arch tower section is circular cross-section, the entire bridge has a higher base frequency, rigidity is greater. This paper also conducts a preliminary analysis for the bridge vibration mode, providing a certain reference for the construction of these bridges.
